pretty poor "logic" for someone that claimed to be a scientist if you ask me. If you believe that the universe as we know it started with a "big bang" and then sentient beings evolved then it stands to reason that one had to be the first. Why can't it be us? Why wouild anyone assume that other worlds evolved faster than us?

I have never claimed to be a "scientist" - perhaps you missed the /sagan part indicating I was paraphrasing what I believe to be a carl sagan-ific look at things?
